Confused about whether you owe tax on your savings? You're not alone. The rules involve multiple overlapping allowances. Here's the complete, clear guide for 2026. Updated April 2026

The Simple Answer: Three Layers of Protection

Most UK savers are protected by up to three allowances before any tax is due on savings interest. Understanding which ones apply to you is the key:

How the Allowances Stack Up in Practice

Example 1 — Employed basic rate taxpayer earning £30,000:
Non-savings income: £30,000 — well above £17,570, so no starting rate for savings. PSA: £1,000. Tax-free savings interest: £1,000. Any interest above £1,000 taxed at 20%.

Example 2 — Pensioner with £10,000 State Pension:
Non-savings income: £10,000 (below £12,570 personal allowance). Starting rate for savings: £5,000. PSA: £1,000. Total tax-free savings interest: £6,000. Only interest above £6,000 is taxed.

Example 3 — Higher rate taxpayer earning £65,000:
PSA: £500 only. Interest above £500 taxed at 40%. A 4.5% savings account would breach this threshold with just £11,100 in savings.

Savings That Are Always Tax-Free

How HMRC Collects Tax on Savings

Banks automatically report all interest paid to HMRC. HMRC then adjusts your PAYE tax code the following year — reducing your personal allowance to collect any tax owed on excess savings interest. You don't receive a bill or need to do anything proactively if you're employed or receive a pension. Self-employed taxpayers report savings interest on their Self Assessment return.
